I am on my second muffler and while the perfomance from this one is excellent, I can' hear myself think. Has anyone had any simular problems or had any luck with the exhaust.

 

what kind of muffler do you have?

 

I hate riding in cars where the exhaust is so loud you cant talk to another passenger. Try a Corsa exhaust, nice sound outisde, bot ionside.

 

I had a magnaflow.....loud
Now I have a turbo....louder

 

Can you post a picture please

 

I love the Magnaflow thrushing noise. Besides Mario Andretti endorses them so how could you go wrong? If you wanted quite why didn't you stay with the factory? If you want a quite ride put your factory muffler back on. Besides if you did it for perfomance you didn't gain any useful hp. You would have to change the whole exhaust set up to gain any useful hp. I have known so many idiots in my area that think they are going to make their Japanese car into a race car just by putting on a huge muffler.

 

omgosh that is so true!
wonder who gave them that idea
hey what about Borla?

 

I'm not sure about the exact diamater, but I believe the HHR already has a 2 1/4 inch exhaust. If you changed the entire exhaust only, and did no other mods, I don't care if cost a trillion dollars, chances are that the HHR would probably run like azz. Now, if you take and change the muffler only on that same car you will see a significant improvement. Better flow means more go. Since the exhaust itself is already a large diamater, the only thing restricting it is a stock muffler. Please have a clue before making comments.

 

This is a perfect example of why my responses to people on here are negative most of the time. You have to be out of your mind if you think just replacing a muffler is going to net your a larger power increase than a catback. Think you need to take your own advice about getting a clue before making comments.

 

Read the reply. "cat back only". No intake, no header,, no anything. It's called back pressure, look into it. I suppose the fact that an exhaust specialist verified what I am saying means nothing to you mr. midas. To be clear here we are talking about an HHR and nothing else. It is true that other cars come with other variances in diamater and the exhaust may be too small in which case I would be incorrect. Not the case with the HHR in which the exhaust is more than sufficient And I am correct. The reason you make negative comments is because you are an azz, plain and simple no other reason
